Another one of the backgrounds used in the Aquann Castle,from Ganbare Goemon 4. This one in particular is used in a shooting gallery, where Yae must used the enemy shooter to destroy some targets, so she can proceed even further in this bizarre place. It has a glass window that shows that the forstress of Aquann is underwater. An HDMA is included with it too.
Uses palette 3 and 4. Only BG2 slot. LG4 slot for layer 3.
